Abstract


Our country is a country with serious drought. Per capita fresh water resources isquite poor, and the use of the increasingly serious water pollution not only reduces thewater functions, further aggravated the contradiction of water shortage. Meanwhileenergy shortage is a global problem, the two major problems of China is implementingthe strategy of sustainable development has brought serious impact, but also a seriousthreat to the people’s drinking water safety and health. With the development ofeconomy, medium cities construction by leaps and bounds, building energyconsumption and water consumption are also increasing year by year, therefore, energysaving, water saving is very important. In this article, through field research of energyconservation in building water supply and drainage water saving technology and itsapplication situation. From the drawing design, the product material selection and itssite construction, water-saving energy-saving feasibility is discussed.Along with the development of science and technology progress, step by step,many energy-saving water saving technology has also been developed and applied toour real life, now in the building water supply system, adopt the way of variablefrequency speed regulation constant pressure water supply pump group has become themainstream. For building water supply equipment modification also plays a big role inenergy saving.Frequency conversion constant pressure water supply system in the building watersupply, this paper analyses and discusses the application of first access to existing literature and data this paper expounds the working characteristic curve of pump andprinciple of work, understand the causes of variable frequency pump can achieve energysaving. Second is the development status of China’s current water supply and drainage,lists several kinds of commonly used feed system now, there are direct water supplysystem, set up high level cistern water tank water supply system of water supply system,water pump, pipe network overlying water supply system, etc. Then analyzed theprinciple of variable frequency speed regulation constant pressure technology and thesystem composition, and the application of the technology in the building water supplysystem. Through case analysis, we can see: variable frequency speed regulation constantpressure water supply technology in some buildings water supply system can reallybring energy saving effect of water saving. And the effect is remarkable in terms ofsafety and economic benefit of water supply. Therefore, variable frequency speedregulation constant pressure technology in building water supply system has importantpractical significance.
